[0028] Example

[0029] A method for preparing an antibacterial plaster model for dental use includes the following steps:

[0030] S1. Purification treatment: prepare phosphate rock into a certain slurry, filter out bulk impurities and suspended matter, add dilute sulfuric acid for neutralization reaction, remove a small amount of insoluble oxides, calcium carbonate, magnesium carbonate and other impurities to make it It is converted into soluble salt, and organic carbon is filtered at the same time. After adding quicklime for neutralization, it is crushed and ground into gypsum powder;

[0031] S2, crystal conversion reaction, put the gypsum powder in a slurry mixer, add sulfuric acid and phosphoric acid mixed acid aqueous solution according to a certain solid-to-liquid ratio, mix uniformly to prepare a mixed slurry, and then add a certain amount of crystal conversion agent , And finally add sodium acetate as an admixture to form a saturated solution system, so that the slurry und...

Abstract

The invention discloses a preparation method of an antibacterial plaster model for the dental department. The preparation method comprises steps as follows: S1, purification treatment: certain slurryis prepared from phosphate ore, large impurities and suspended solids are filtered out by a screen, dilute sulfuric acid is added for a neutral reaction, a small quantity of impurities such as insoluble oxide, calcium carbonate, magnesium carbonate and the like are removed and converted into soluble salts, meanwhile, organic carbon is flirted out, after quick lime is added and neutralizing treatment is performed, a mixture is crushed and ground, and plaster powder is obtained; S2, crystal transformation reaction: the plaster powder is put in a mud mixer, and added to a mixed aqueous solution of sulfuric acid and phosphoric acid in a certain solid-liquid ratio, uniform mixing is performed, mixed slurry is prepared, a certain quantity of a crystal modifier is added, finally, sodium acetate is added and taken as an admixture, a saturated solution system is formed, and the slurry is subjected to the crystal transformation reaction. The preparation method has beneficial effects as follows:the raw materials for the antibacterial plaster model for the dental department can be stirred more sufficiently, and efficiency of model forming work can be increased.

Description

technical field [0001] The invention relates to the field of gypsum models, in particular to a method for preparing a dental antibacterial gypsum model. Background technique [0002] The model gypsum is mainly made of calcium sulfate hemihydrate with α-type structure and appropriate additives such as pigments. Gypsum mold is a traditional mold that has been used in industrial production for a long time. The basic material in casting production based on grouting molding—forming mold has become an important factor restricting casting type, regularity, labor productivity and production cost. Plaster mold is The traditional molds that have been used in industrial production for a long time, the basic material in the casting production based on grouting molding, the forming mold has become an important factor restricting the casting type, regularity, labor productivity and production cost, while the sanitary ceramics industry uses Forming molds mostly use gypsum models. Although...
